God, through Christ Jesus, has sent His Holy Spirit to abide in every believer. One of His titles and ministries is that of Comforter.
He comforts and encourages like no natural human can and then enables those who have been comforted to become supernatural comforters themselves.
God, in Christ Jesus, is an able Comforter in that Jesus suffered all of humankind’s persecutions, torments, temptations and concerns, yet without sin. He is therefore well able to minister to all who call upon Him.
